4 cards from this section. Quick, good the night before a test.
What is the relationship between pressure and depth in a fluid?
Think about the weight of the fluid above.
Define buoyancy in your own words.
Think about why boats float.
What causes the pressure in a fluid to increase with depth?
Think about the concept of fluid weight above a point.
True or False: The center of pressure is always located at the physical centroid of a submerged area.
Consider how pressure acts differently at various depths.
A submerged cylindrical object has a diameter of 0.5 m and is 2 m long. Calculate the total downward force due to fluid pressure acting on the curved surface of the object when submerged to a depth of 5 m.
Use the formula A = πdh to find lateral area.
Describe how changing the angle of inclination of a submerged surface affects the center of pressure and resultant force.
Visualize the surface tilted to see how pressure varies.
